Royal Canadian Air Force Sees More Sims In the Future of Fighter Pilot Training

dakohli writes "Currently, Canadian Fighter Pilots spend about 20% of their 'stick' time in Simulators. RCAF General Blondin states that this will rise to 50/50 in the future. The article goes on to state that the U.S. Army is moving in this direction, although the U.S. Air Force is a little more skeptical. Aircraft are expensive to fly, and if the fidelity of a simulator is good enough then perhaps real pilots will spend even less time actually in the air. Slashdotters, do you think that this will actually make recruiting pilots more difficult, or is it a sign of the things to come beyond Military Aviation?"

The fidelity is already there. Flight time in the sim is nearly as good as the real thing, especially considering when you are up on a motion platform.

The sims are great for procedure training since you can simulate failures which would be expensive or impossible to simulate in a real aircraft. More sim time = less cash spent on keeping the real aircraft in the air but with the same amount (or more) experience for the pilot being retained.

Given the number of hours things like the F22 have managed to stay airworthy I'd say simulators were the future, yes.

Why not?

[pushing-robot]

In a decade or two, most of them will be flying drones anyway.

No, it's really not.

For the record, I'm a military aviator, and I've got plenty of experience in both sims and the actual aircraft.

For some platforms, yes, the sims are just fine. Less dynamic platforms (i.e. helicopters, big wing) work just fine with full motion platforms. It will never be "perfect." Many of the imperfections manifest in ways that are inherent in simplified programming, i.e. actually modeling fluid dynamics for how the jet handles with failed systems vs. just hard coding that things "will" or "wont" work at certain airspeeds.

For tactical aircraft, however, there is absolutely no comparison. Yes, basic flight operations (taking off, landing, navigating) can be done relatively decently, but tactical flying (g-force, sun blind spots, etc) cannot be replicated in anything remotely resembling our current simulators.

Not to mention that most tactical simulators dont include motion. A "full motion" sim can't replicate more than 1.0 G in any given direction, much less a sustained 5g pull. The technology simply doesn't exist.

So do simulators have their uses? Absolutely. But there is no substitute for real flight time, and until we get some Star Trek -esque technology at our disposal, there won't be.

For the record, I'm a commercial pilot.

Simulators have their place - but it is certainly nowhere near the experience as a real aircraft. Speaking from a commercial background, simulators are great at two things:
1) Procedure
2) Techniques

Simulators are great in showing pilots how things work. Want to know what to expect in a fogged in approach to an airport and are learning how to use the ILS etc? A simulator is *great* in this role. You can do things in this combo that are GREAT for education. Does it come anywhere close to the real thing? Hell no.

The other thing that simulators excel at is teaching things such as instrument scans - basically train you to keep an eye on all your instruments at the same time by developing an effective scan of them. No pilot flying on instruments will use a single instrument - flying is very complex and cannot be done like this. An effective instrument scan (A/H -> Airspeed -> A/H -> Altitude -> A/H -> VSI -> A/H -> DG etc) is very hard to grasp when first starting - and it is the bread and butter that keeps pilots alive when the weather is starting to deteriorate or you start to fly faster and bigger aircraft.

Your standard 737 pilot will probably spend about 15 minutes out of every flight looking out the windows. The rest is monitoring instrumentation. I cannot understate how important this skill is - and simulators are perfect at developing those skills.

So are simulators replacement for a real aircraft though? Nowhere near. Simulators should be treated as an addition to inflight training - not as a replacement for it.

\Not true. IEEE 1278.1-1998 DIS has been out for a long time (first version of the spec in 1993). It is designed to have massive numbers of interacting agents. Even on a Pentium II you could get a thousand clients connecting. How do I know this? I'm currently writing a multi-threaded cross-platform modern jet combat simulator (using Java 7+OpenGL/JOGL+OpenAL+JInput+OpenDIS, if you must know) and having a lot of clients and CGF (Computer Generated Forces) is well within the capabilities of one of the 8-core AMD CPUs you can get. The performance of OpenGL and modern multi-threaded Java is outstanding (compared to the existing single-threaded C++ jet combat simulations currently on the civilian market; the DCS series and Falcon BMS).

My understand is that many military aircraft these days (and certainly the simulators) have hardware support for IEEE 1278.1 so pilots can learn to operate cockpit in a massively networked environment. Hence, it appears your post is speculation rather - because the military have been able to have extensive simulated engagements for a long time - although a particularly royal air force was interested in the characteristics of the 80-player (40 a side) battles we were able to host in the Eagle Dynamics Flaming Cliffs 2 simulator.

If you're looking out the window for your enemy in a modern air combat situation, you're either about to die or lots of people screwed up in lots of ways.

Nobody has given much thought to non-BVR air combat in about 10 years and for good reason. First sight, first shot, first kill. That's the whole idea of stealth and advanced detection systems for fighters: I'm harder to see, so I see you first, so I shoot first, so I go home minus one long range missile. That's why a $140 Million F-22 makes more sense than three $40 Million Eurofighters. Once the fight is over, nobody got within 40 miles of an enemy and all you have to tally up is the cost of three planes and three trained fighter pilots versus the cost of three missiles and some gas.

Re:No, it's really not.

A previous company I worked at helped create 1278.1 (DIS). And you're correct that it's able to handle massive numbers of simulated entities interacting (easily tens of thousands; I think they managed one sim with over 100,000 entities in the mid-1990s). The crucial difference from the simulated shared environment most of us are familiar with (online games) is that the participants don't cheat. Hacking your client so it doesn't operate as programmed defeats the purpose of running a sim. Whereas in a game it's frequently in the player's best interest to cheat by hacking their client.

So in an online game, all the position, movement, actions, and collisions have to be handled by a centralized server to make it impossible to cheat. With DIS, each client calculates its own interactions and simply multicasts the consequences (e.g. movement changes) to all the other sim participants. e.g. The F-16 sim tells everyone it drops a bomb from its location with this trajectory. The M1A2 tank sim uses that to calculate that it was hit and destroyed, and it tells everyone "I'm dead now."

Since all these calculations are distributed, your computing power scales with the number of participants, unlike an online game where the server computing power is fixed. And the primary limitation on scalability is how much traffic the network can handle (the spec calls for a very minimal packet size, and a lot of work went into decreasing the frequency with which an individual sim needed to multicast updates).

"since the vietnam war"
There also hasnt been a real air war since Vietnam, and yet there's still be a few dogfight incidents.
Missiles fail, missiles can be jammed/countered/evaded. What happens then? More missles? You can only carry so many. Turn and run? Not always tactically viable, and makes you a nice big target.

Sensors can be evaded, thus negating the BVR combat space, letting him get that much closer and taking you by surprise. they can be vectored in on a blind spot (we dont -always- have AWACS radar coverage), they might appear from below you (particularly zoom climb interception profiles, aircraft that were never BVR to start with). hell, that's pretty much the whole concept behind stealth: to negate the other guys detection abilities and get him by surprise. As more and more stealth planes appear, as was bound to happen, it decreases the usefulness of the BVR-only concept, once again pointing out how focusing just on BVR will bite you in the ass.

Point is, you cannot, just CANNOT, tunnelvision on just one tactic. You must remain flexible, you must not leave a backdoor wide open. And that is why to this day we still teach dogfighting tactics, perhaps even moreso than BVR combat training (because it's more complex, and less forgiving).

You cannot build a giant nearly invulnerable death machine, and then ignore the thermal exhaust port that leads directly to the reactor core, even if it is only 2 meters wide.

Re:Don't follow the Canadian example

[Dzimas]

Canada's military spending ranked 14th in the world in 2012. There are 180 nations in the world that spend less on their militaries - hardly chronically underfunded. Canadian soldiers are dedicated and extremely hard working; your attempt to slander the present day Canadian Forces because of an event that occurred 20 years ago is ridiculous. We are not proud that two Canadian soldiers beat a teenager to death in Somalia in 1993, but they don't represent the 115,000 active and reserve personnel in today's CF in any way, shape or form.

simple solution

[aapold]

Simple solution...to prevent jamming... put the simulator... inside the drone!

For the record -- why do we still need pilots?

[rocket rancher]

I'm a private pilot with a multi-engine rating. Simulators seem to be a good way to rehearse cockpit procedures, but unless they figure out a way to simulate g-forces, that's about the limit of their usefulness. Simulating a spin recovery procedure is one thing, doing it for real with a two- or three-g load from the spin is another. With that said, I don't think commercial and military pilots are going to have a viable career field for much longer. Military pilots are already being replaced by drone operators, and I think the rate of replacement is going to accelerate if the drone program keeps posting the kind of successes it has enjoyed so far. Unmanned vehicles seem to be the future of military aviation. Commercial pilots will probably last longer, because commercial airlines have to convince a skeptical public that airliners are going to be as safe with a computer at the stick as they are right now with a human. Realistically, commercial pilots have a hand on the stick only during takeoffs and landings, but all modern heavies can land and take off under autopilot, and have been able to for about thirty years. IIRC, a Douglas Skymaster made a transatlantic flight completely on autopilot, including the take-off and landing, even farther back than that (late 1940s? have to google that) so the technology is definitely out there. IMHO, pilots are still in commercial cockpits (and will be there for a while) because the paying public wants them there, not because they need to be there.
